Answer:

5\frac{1}{2}\ mi

Step-by-step explanation:

we know that

1\frac{3}{8}\ mi=\frac{1*8+3}{8}=\frac{11}{8}\ mi

She drove from her house to the airport and back 2 times

so

Multiply the distance from her house to the airport by 4

(4)*\frac{11}{8}=\frac{11}{2}=5\frac{1}{2}\ mi

Question
Goryan [66]

Given:

(2, 4) and (3, 3) are on the line.

To find:

The equation of line in point slope form.

Solution:

If a line passes through a point (x_1,y_1) with slope m, then the point slope form of the line is

y-y_1=m(x-x_1)

(2, 4) and (3, 3) are on the line. So, slope of the line is

m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{3-4}{3-2}

m=\dfrac{-1}{1}

m=-1

The slope of a line is -1 and it passes through (2,4). So, an equation in point slope form is

y-4=-1(x-2)

Therefore, an equation of the line in point slope form is y-4=-1(x-2).

What are the answers for these 11, 14, 15, 16 and 20.
Vesna [10]

Answer:

11. (x, y) -> (7, -3)

14. (x, y) -> (-3, -2)

15. (x, y) -> (-3, 2)

16. (x, y) -> (7,6)

20.(x, y) -> (4, 1)

Step-by-step explanation:

11.

x + 3y = 1

-3x -3y = -15

-2x = -14

/-2    /-2

x = 7

x + 3y = 1

7 + 3y = 1

-7        -7

3y = -6

/3    /3

y = -2

(x, y) -> (7, -3)

14.

-3x + 3y = 3

-5x + y = 13

-5x + y = 13

+5x     +5x

y = 5x + 13

-3x + 3(5x + 13) = 3

-3x + 15x + 39 = 3

12x + 39 = 3

    - 39   -39

12x = -36

/12    /12

x = -3

Now, we solve for y:

-5x + y = 13

-5(-3) + y = 13

15 + y = 13

-15      -15

y = -2

(x, y) -> (-3, -2)

15.

6x + 6y = -6

5x + y = -13

5x + y = -13

-5x         -5x

y = -5x - 13

6x + 6y = -6

6x + 6(-5x - 13) = -6

6x -30x - 78 = -6

-24x - 78 = -6

       + 78  + 78

-24x = 72

/-24     /-24

x = -3

Now, we solve for y:

6x + 6y = -6

6x + 6y = -6

6(-3) + 6y = -6

-18 + 6y = -6

+18       +18

6y = 12

/6   /6

y = 2

(x, y) -> (-3, 2)

16.

2x + y = 20

6x - 5y = 12

2x + y = 20

-2x     -2x

y = -2x + 20

6x - 5y = 12

6x - 5(-2x + 20) = 12

6x + 10x - 100 = 12

16x - 100 = 12

    + 100  +100

16x = 112

/16    /16

x = 7

Now, we solve for y:

2x + y = 20

2(7) + y = 20

14 + y = 20

-14      -14

y = 6

(x, y) -> (7,6)

20.

-2x - y = -9

5x - 2y = 18

-2x - y = -9

+2x     +2x

-y = 2x - 9

/-1    /-1

y = -2x + 9

5x -2y = 18

5x - 2(-2x + 9) = 18

5x + 4x - 18 = 18

9x - 18 = 18

   + 18   + 18

9x = 36

/9  /9

x = 4

Now, we solve for y:

-2(4) - y = -9

-8 - y = -9

+ 8     +8

-y = -1

/-1  /-1

y = 1

(x, y) -> (4, 1)

Hope this helps!
